Can I ground a turntable to a receiver with no built in ground wire?

[tennesseeborde]

I just bought a used Ion Profile Pro turntable with no ground wire. I'm getting hum, and based on my research I think I need to ground it to the receiver. Any suggestions on where to attach the ground wire to the turntable?

It certainly sounds like grounding may be a possible cause. Most turntables have a grounding wire which can be connected to the amplifier's ground terminal. All the decent ones I've seen have.

Is it possible one of the ground wires to the cartridge has come adrift?
